ClGAR-BUNCHING MACHINE.

Specification of Letters Patent.

Patented Jan. 29, 1907.

Application filed March 22.1906- Serial No. 307,524-

and ARTHUR W. DAvIs, both citizens of the United States, residing at Cranston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Cigar-Bunching Machines, of which the following is a specification, reference being had therein to the accompany ing drawings.

Our invent-ion relates to machines for bunching and applying the binder to cigarfiller tobacco, and has for its object the ends commonly sought in this class of machinery, but more particularly to provide a compact mechanism capable of great speed andhaving the capacity of forming a homogeneous bunch in any desired variety of form and from any variety of filler.

Our invention consists, essentially, in the improved feeding mechanism and in the novel construction and operation of the bindingrolls. I

Further novelty resides in the peculiar construction and combination of mechanical parts coacting with and auxiliary to the feeding and binding mechanism.

In the drawings, wherein like reference characters indicate like parts, Figure '1 is a side elevation of a complete machine embodying our invention; Fig. 2, an elevation of the opposite side of the same with a portion of the feed-trough broken away; Fig. 3, a front elevation of the machine with the ironingplate removed; Fig. 4, a plan view with a art of the trough broken away Fig. 5, a ongitudinal central section of the same. Fig. 6 is a like section of the carrier-rolls and adjacent parts, showing the rolls inreceiving position; Fig. 7, the same showing the rolls in discharging position; Fig. 8, a side view of a feeding-bar; Fig. 9, section on liner a: of Fig. 3; Fig. 10, longitudinal section, partly in elevation, of one of the forming-rolls; and Fig. 11, a modified form of roll.

Like reference-numerals indicate like parts throughout the views.

The machine selected to embody the invention comprises a bed 1, supported by a frame 2, in which is mounted a driving-shaft 3, actuated by a ulley 4 and carrying a gear 4, which mes ies with a toothed wheel 5, mounted upon a stud. 6 in'the frame.

the wheel is a gear 7, engaging a toothed wheel 8, fixed to cam-shaft 9. The camshaft may be driven, if desired, directly from the driving-shaft. The shaft 9 actuates the various mechanisms for feeding, conveying, and forming and binding.

The feed-trough is supported by arms 10 upon the back of the machine-frame and comprises walls 11, carrying the usual rollers 12 and 13. The latter is an idler adjustable longitudinally in the walls .by screws 13. The feed-belt 14, carried by the rollers, rests upon a board 15 in the trough. Upon each wall 11 is a guard-rail 16, transversely adjustable by screws 17 in lugs 17 and 17 upon the rails and walls, respectively. In alinement with the belt 14 is a receiving plate or table 18, fixed in. the uprights 19 of the frame. Vertically adjustable in the uprights is a transverse bar 20, to which is fixed by screws 21 the inner ends of a series of interspaced flat bars 22 22, whose opposite ends are fixed to a cross-bar 23, supported on lugs 24 upon the trough-walls. This bar series forms a fixed guiding-grate, whose lower surface is slightly inclined and provided wit-h a double swell 22 and 22 The inclination and swells regulate the density of the filler-sheet during its advance toward the knife. The thickness of the filler-sheet is further gov erned by adjusting the bar 20, which has two vertical slides or strips which traverse openings 20 in a plate 20 fixed to the uprights. The bent ends of the slides carry adjusting-screws 20 which rest upon the plate 20 An important auxiliary device for advancing the filler-sheet is a carriage or frame comprising guides. 25 with oblong openings 26 to permit the passage of a shaft 27. Extensions or guides 28 upon these sides have horizontal slots 28. Sliding plates 30 .upon the inner faces of the guide plate are joined by screws 31, traversing slots 28, with companion sliding plates 32 upon the opposite sides of the guide-plate. The plates 30 are connected by two transverse bars 33. The described carriage is reciprocated .by the shaft 27, which is mounted in vertically-slidable blocks 27, moving in guides 25 upon the machine-frame. Pivoted to each block is a connecting-rod 27 connected to a lever 27 fixed to a rock-shaft 27 mounted in the machineframe. The shaft 27 is oscillated through its arm 27, whose end carries a stud 27 traveling in a channeled cam 27*, fixed to cam-shaft 9. Loosely mounted upon the transverse bars 33 of the carriage and sliding in the spaces intermediate the bars 22' 22 are a series of flat, serrated, or toothed feeding-bars 34 34, each of which has, as shown in Fig. 8, a post 34 and a slot 34", which permits longitudinal movement upon the bars 33, which pass therethrough. Each of the bars 34 has teeth upon a portion of its lower margin. The rear marginal portion of the bar is in a higher planethan its forward portion. Each alternate bar of this series has teeth 34 upon the higher or rear margin and one or two teeth 34* upon its opposite margin. The other bars of the series have teeth 34 throughout their forward lower margin in addition to the teeth 34 on their rear margins, as shown in Fig. 6.

Traversing each bar-post is a threaded pin 35, provided with an adjusting-nut 35. To the pin is attached a retractile spring 36, whose opposite end is fixed to a transverse strip 36, connecting the sliding plates 32. On the plates 32 are studs 37, connected by links 38 to the ends of levers 39, fixed to the shaft 27 moving in slots 40 of the standards 19. Upon one end of the shaft 27, as shown in 2, is fixed an arm 41, connected by a rod 42 to an intermediate portion ofthe lever 43, loosely mounted on the rock-shaft 27 The lever 43 is provided with a stud 44, trav- In Fig. 7 the carriage is shown elevated at the extreme'of its rearward travel. It first descends and travels-forward in a plane parallel with and slightly above the receivingtable 18, as shown in Fig. 6. It next rises to elevated position preparatory to repeating its rearward reciprocation. During the forward travel of the carriage the teeth of the feeding bars 34 project below the horizontal plane of the grate bars 2222.

The feeding-belt 14 is actuated by the roller 12, mounted on a shaft 12, journaled in circular plates 12 fixed in the feed-trough walls. Fixed to the shaft 12, as shown in Fig. 2, is a ratchet 46 and an arm 47, carrying a pawl 48. The latter is pressed by a spring 48 into engagement with the teeth of the ratchet. A rod 49 connects the end of the arm 47 to one end of a bar 50, pivoted intermediate its length to the upperend of a bar 51, whose lower end is pivoted to the lever 43, which intermittently rotates the roller 12,

advancing the belt 14 synchronously with the advance of the feeding-rack. The fillersheet in the trough is thus intermittently advanced.

For separating each charge from the fillersheet a knife 52 is slidably mounted in the uprights 19. The knife is provided with rack-teeth 52 52 and a blade 52 whose cutting edge. slides slightly below the plane of the receiving-table 18, as shown in Fig. 6. Mounted in the uprights adjacent the knife is a shaft 53, to which are fixed toothed segments 53, enga ing the rack-teeth 52.

Upon the end of s aft 53 is an arm 54, connected to the upper end of a connecting-rod 55, whose lower end is pivoted to a cam-lever 56, loosely mounted on the rock-shaft 27 On lever 56 is a stud 56, traveling in the channel of a cam 57, mounted on the camshaft 9. By this cam the segments 53 vertically reciprocate the blade 52 which is timed to descend at the close of each advance of the belt 14 and feedrack. A transverse bar 57, mounted in the uprights contiguous with the blade 52 assists to retain the latter in shearing contact with the margin of the feeding plate or table 18.

The mechanism for receiving the charge from the table and conveying it to the binding or forming rolls includes a shaft 58, mounted in the uprights 19, to which is fixed a conveyer comprising an oblong box 58 with an open top and bottom, containing a slidable block 58 in which is fixed the ends of a yoke 58, which slide through diametrical passages in the shaft 58. The yoke-head is provided with a transverse opening 58 one side of which is formed by a bar or frictionroller 58 The box 58 oscillates in a quarter-circle from the feeding-table, where it receives'the filler charge, to discharging position and return, as shown in Fig. 6. This movement is imparted through shaft 58, which is provided. with an arm 59, pivoted to a connecting-rod 60, attached to the end of a cam-lever 61, loosely mounted on the rockshaft 27 and carrying a stud 61 which travels in a channeled cam 62 on the 'cam-shaft 9. The conveyer-discharging mechanism comprises a shaft 63, j ournaled in the uprights, to which is fixed two arched arms 64 64, connected by links 64 64 to a slide 65, moving in vertical guides 65 in the uprights. Fixed to the slide is a projecting curved guide-bar 65 provided with a transverse loop 65 (best shown in Fig. 6,) which bar is adapted to traverse the opening 58 in the dischargeyoke 58. The curved guide-bar 65 is vertically reciprocated as follows: The shaft 63 is provided with an arm 66, to which is pivoted a connecting-rod 67, connected with the end of a cam-lever 68, loosely mounted on the rock-shaft 27 and having an intermediate stud 68, traveling in a cam 69, mounted on cam-shaft 9. The downward thrust of the slide through the described connections occurs after the yoke 58 has reached a vertical position in alinement with the slide 65, (shown in broken lines in Fig. 6,) whereby the discharge-block 58 is downwardly impelled to expel its filler charge into the forming-chamber. A curved guard-plate in the uprights retains the charge in the conveyer during the latters downward travel.

Referring to forming or binding chamber, the front of the machine-frame is provided with bearing-plates 71 71, each having four segmental slots 72 72, the plate 71 forming one bearing of the shaft 73, whose end is journaled in the standard 74 upon the machine-frame, and the plate 71 forming a bearing for the driving-shaft 73, journaled in a second support 74. To the respective shafts are fixed gears 75 and 75. Motion is communicated from the shaft 73 to the shaft 73 through a shaft 76, mounted in the bearing-plates 71 71, one of whose ends carries a gear 77, meshing with the gear 75, and whose other end has a gear 7 7 engaging the gear 75. Sliding along the inner faces of the bearing-plates are crescent-shaped opening and closing jaw-couplets 78 .79 and 80 81, connected, respectively, in couplets by rods 82 and 83. Mounted in the jaws 78 and 80 are three forming-rolls 84, 85, and 86 and in jaws 79 and 81 the rolls 87 88 89. Upon the rolls adjacent each end are the pinions 84 84 85 85 &c., respectively. In structural detail the rolls are similar. As shown in Fig. 10, the roll comprises a two-part core whose sections 89 and 89 are detachably interlocked by an end projection 89 on section 89, registering in a cavity 89 in the end of section 89 The particular form of interlocking, however, is not exclusive. section of the core, which is rigid, is preferably bent intermediate its length. Mounted loosely upon the sections 89 and 89 respectively, and with their inner ends. abutting are two tubes 89 and 89 The outer surfaces of the tubes are longitudinally corrugated or otherwise roughened. Soldered to outer end of tube 89 is a flexible spirallywound sleeve or connection attached to the pinion 89. A similar flexible connection or sleeve is soldered to the outer end ofthe tube 89 and fixed to the pinion 89 The roll shown in Fig. 10 is arranged to roll a cigarbunch having a uniform body diameter; but when a perfecto shape is desired each core is inclined in relation to the other, as shown in Fig. 11, and the peripheries of the tubes are somewhat concaved longitudinally. Upon the inner ends of shafts 73 and 73 are gears and 90, respectively. The gear 90 meshes with and drives the pinions 84, 85, 86, 87, 88, and .89, and the gear 90 drives the pinions 84 85 86 87 88 and 89 Each ' The'opening and closing jaws oscillate from receiving to discharging position, as shown in Figs. 6 and 7, by virtue of the following connections. (Best seen in Fig. 5.) Guides 92 and 93 in the frame carry slides 94 and 95. The slides have, respectively, lateral lugs 94 and 95. The lugs 94 are connected with the jaws 78 and 79 by links 94 and lugs 95 are connected to jaws 80 and 81 by links 95 Connecting-rods 94 and 95 join the slides 94 and 95, respectively, with the levers 94 and 95, fixed to-a rock-shaft 96 in the frame. One end of the rod 50 above referred to is pivoted to the guide 92. The rock-shaft 96 is oscillated by means of a link 97, connecting the lever 95 with the end of a lever 98, pivoted 'to shaft 27 and provided with a stud 98, traveling in a channeled cam 99. The j awcouplets are normally pressed toward each other by springs 100, bearing against their margins.

It is desirable that the forming-rolls should be inactive during the interval between their delivery of one bunch and the insertion of another charge. For attaining this end the shaft 93,- which drives the forming or binding mechanism, is provided with a loose driving-pulley 101 which is inter mittently thrown into operation by the following clutch mechanism: A longitudinallyslidable bar 102 is mounted in the bed of the machine, as shown in Fig. 3, to which is fixed an arm 103, engaging a collar 104, slidable on but rotatable withthe shaft 93 and adapted at the extreme of its outward travel to engage lugs 104 upon the face of pulley 101. Loosely mounted on the bar 102 is a depressing-plate 105, carrying a stud 105, contacting with the irregular edge of a bar 106, fixed to the connecting-rod 95 by which it is reciprocated, to throw the collar in and out of engagement with the pulley 101. The stud 105 is pressed against the face of the bar 106 by a retractile spring 107, connecting the plate 105 with the machine-frame. The pulley or wheel 101 is driven through a belt 108 by a wheel 109, fixed to shaft 3. The ironing table or plate 110 is mounted upon the "machinebed adjacent and in the plane of the upperforming-rolls, and the deliverychuck 111 (shown in broken lines in Fig. 3) is fixed to the bed below the rolls and leads from an opening 112 in the bed. I

From the foregoing description it will be observed that the filler material is spread in the form of a sheet upon the belt 14 in the feeding-trough, where it is intermittently advanced toward the grate, the swelled and TOO inclined lower portions of whose bars 22 serve to smooth and gradually lessen the thickness of the sheet as it progresses. Simultaneously with the advance of the feedbelt the rack through its toothed bars 34 engages the filler-sheet and advances the same the distance of a carrier-charge into the carrier-box 58, the teeth being in a continuous transverse series serving to ad vance the whole breadth of the filler-charge at one time, thereby preventing all torsion of its constituents parts. Furthermore, the yielding possibilities of any one or more of the toothed bars by virtue of the springs 36 prevents any derangement of the advancing filler occasioned by the presence of any obstructin bunch. At the close of each advance of the sheet the blade of knife 52 descends and cleanly severs the carrier-charge, whereupon the carrier swings from its horizontal to vertical or discharging position above the forming-rollers S4 and 87, which at that instant are distended to receive the charge expelled by the sliding block 58 Meanwhile the operator feeds the bunchbinder along the ironing-table 110, the roll 84:, and into the forming-chamber intermediate the two sets of rolls, which simultaneously forms and applies the binder to the bunch.
